' Specification of Letters Patent. Patented June Application filed July 15, 191a. Serial No. 310,962.

To all whom it may concern: I

lie it known that I, {ISAAC FinioUsoN, a citizen of the United States of America, reshiing at Shelby, in the county of Richland and State of Ohio, have invented certain new an d useful Improvements in Power Hoisting and Conveeying lVI-achines, of which the following is a specification.

This invention relates to a power hoisting and conveying machine.

The primary object of the present invention is to provide a power operated mechanism to lift a load of material such as a corn shock or the like to a higher or lower plane and. deposit same at any predetermined pointof the radius of the free end of the rotatable hoisting and conveying mechanism. 1

The invention further comprises means of rotating the lifting mechanism in either direction and for conveying the load or material to predeterminedpoints of the radius of its travel and means of raising and low ering the lifting arm and load to predetermined heights.

.These. and other objects are attained by the mechanism shown in the accompanying drawings in which: m

Figure 1 is a plan view of an assembled machine.

Fig. 2 is a side elevation of the machine with a portion of the frame-work removed to show the train of reversing gears.

F 3 is a section of the machine on the line 33 of Fig. 1.

Fig. 6 is a detail sectional view of the ball racethat supports the lifting .mechanism.

Fig. 7 is a side elevation of the frame work of the machine and upper portions of the lifting mechanism.

Fig. 8 is a detail viewiof one of the spindles upon which the reversing gears are mounted.

In the drawings reference numerals 1, 2, 8, f, 5 and 6 represent members of the main frame-work of the machine which is preferably made of wood or iron. I

The main frame-work Ts provided with an auxiliary framework A which is so 1omechanism and arm.

. cated as to position the top thereof upon a lower level than the top of the main frame to permit the free rotation of the lifting (See Fig. 7.) The combined lifting and conveying mechanism is mounted upon the bottom 7 of the auxiliary frame-work, and is constructed as follows:

A tubular standard 8 is provided with an annular flange 9 which is fastened to the bottom 7 of the auxiliary frame-work by bolts 10 .or the like thereby maintaining thestandard in a vertical position. The upper or-end portion 11 of the standard is provided with an annular flange portion (nut or washer) and the top face thereof is grooved to form one-half of a ball race 12. A washer 11" is interposed between the ball race .for'wearing purposes. A rotatable member .13 preferably made smaller in diameter than the standard is telescopically fitted within the interior of the standard and is supported for'rotation on a flange, nut or washer 14: which is provided with a groove 15 complementary to the groove 12 thereby completing the ball race for supporting the rotatable member 13. A lifting and conveying arm 14 is secured to the rotatable member 13, theend thereof bifurcated and pivotally mounted upon the pin 16. The arm is preferably formed tubular in structure.

A supporting bar 17 ispreferably pro- ,vided with bifurcated ends. 'One end of the supporting bar 17 is 'pivotally attached to the rotatable member 13 by a pin 18 and its opposite end receives and carries a roller '19 upon a pin 19, Links 20 and 21' are mounted upon a pin 22 at one end andtheir opposite ends are provided with a pin 23 upon which a roller 24 is mounted. The pins 22 and 23 are secured to the links 20 and 21 in spaced relation to eachotherto permit the lifting arm 14 tobe interposed therebetween as shown in Fig. 5; The peripheries of the rollers 19 and 24: are preferably grooved to fit the periphery of the lifting arm to obviate undue friction and guide their travel thereon in a direct line. A- secondpair of links '25 and 26 are connected to the links 20 and 21 at one end and their opposite ends receive a roller .27 which is mounted upon a pin28, thereby providing a mechanism to control the lifting arm when operated fromany' source of power. I

To operate the lifting arm 14 and cause it to be positioned at different or predetermined planes so as to lift the load, shock of corn or other material to the height desired to accomplish the purpose intended a cable 29 or the like is attached to cars 30 formed on the rotatable member 13 and first passed over the periphery of the roller 27; thence through an aperture formed in the member 13 over a guide pulley 31; thence in a downward direction through an aperture formed in the lower portion of the member 13 over the periphery of a pulley 32 and around the winding drum 33 to which the free end of the cable is attached, and preferably wound around the drum several times. The cable is normally maintained taut.

Power is applied to the cable for raising or lowering the lifting arm by the following mechanism. Power is transmitted from any source of supply to the pulley 34 which is rigidly secured to the shaft 35 imparting movement to agear 36 which is rigidly mounted on the shaft 35. A jack shaft 37 is journaled to the frame in spaced relation. to the shaft A gear 38 is rigidly secured to the jack shaft 37 meshing with a gear 39 which is rigidly secured to an auxiliary jack shaft 40 which is journaled inbearings provided on a yoke 41. The yoke 41 is pivotally mounted upon the shaft 37.

A driven gear 42 is also mounted upon the auxiliary jack shaft 40 and rigidly secured thereto in spaced relation. Thegear 42 is adapted to engage or mesh with the driving gear 36 when the operator of the lifting mechanism desires to lift theload or material. When motion is imparted to the driving gear 36 through the train of gears described, the gear 43 which is rigidly mounted upon the end of the shaft 37 is rotated imparting movement to the crown wheel 44. The crown wheel 4% is rigidly attached to the vertical shaft 45 and it has rigidly secured thereto a worm wheel 46.

The worm wheel 46 engages a gear 48 which is rigidly mounted on the shaft 4-7 imparting movement to the winding drum 33.

The train of gear ronnections as described with driving gear 36 in mesh with the driven gear 42 imparts movement to the winding drum 33 raising the lifting arm to the height desired by the operator. When the desired height is reached by the lift ing arm the operator grasps the lever 49 which is attached to the yoke 41, withdrawing the end of the pawl lever 50 from the notch 51 in the sector 52 and swings or pivots the yoke on its bearings until the end of the pawl lever reaches the noteh at which time the gears 36 and 42 are dis engaged or in neutral position, and no move ment is transmitted through the gear connections to the winding drum \Vhen the operator desires to reverse the rotation of the wimling drum to lower the lifting arm and its load to a lower plane, the operator grasps the yoke lever 49 swings or pivots the yoke upon its bearings until the end of the pawl lever reaches the notch 54 on the section 52 thereby forcing the driven gear 42 to engage or mesh with .a reversing driving gear which is mounted upon a shaft 56.

Thegear 55 is driven in an opposite direction to that of the gear 36 through. a train of gears 57, 58, 59, and mounted on spindles 61 thereby reversing the rotation of the wii'nling drum unwinding the cable and permitting the load carried by the lifting arm to be deposited at any lower level or plane desired by the operator.

it will thus be observed from the description given and the drawing that means are provided to raise or lower a load or material carried. by the lifting arm to any higher or lower plane desired. Any conventional means can be applied to the free end of the cable to carry or lift theload or material.

A. grappling hook 62 is shown as a conventional means of performing this function.

Description of the mechanism for rotating the lifting mechanism and arm.

To transmit a rotatable movement to the lifting mechanism in either direction for conveying the load or material to a predetermined point of the travel of the lifting arm, a sprocket wheel 63 is rigidly mounted upon the shaft A shaft 64 is mounted on the frame and a sprocket wheel 64' is mounted on the end that projects beyond the frame-work. The sprocket wheels 63 and 64 are connected together by a sprocket chain 65. hen the pulley 34 is driven from any source of power movement is imparted to the shaft 64.

A gear 66 is rigidly mounted upon the shaft 64. A shaft 67 is journaled in bearings provided in the frame-work of the machine extending substantially the full width of the frame-work. A yoke 68 is pivotally mounted upon the shaft 67. and a iack shai' t 69 is journaled thereon. The shaft 67 has a gear 70 mounted thereon which meshes with a gear 71 mounted on the jack shaft A gear 72 is mounted on the jack shaft 69. The gear 72 is adapted to mesh with a gear 66 mounted upon the shaft 64 from which movement is imparted to it, and through the train of gears directly to the shaft 67. A worm wheel 74 is mounted upon the shaft 67 engaging with the gear wheel 75 which is secured to the rotatable member 13. lVhen movement is imparted to the shaft 64 through the train of gears just described the lifting mechanism and arin are rotated the following means are employed:

Movement is imparted to the train of gears 76, 77, 7S audit) which are mounted on the spindles by the shaft 64 to the shaft 81 driving the gear 82 inan opposite direction to that of the ear 66. YVhen the yoke '68 is pivoted on the shaftG? by the operator grasping the lever 83 and pivoting same until the gear 72 meshes with the gear 82 the direction of rotation of the shaft 67 is reversed, thereby forcing the lifting mechanism and arm to travel in an opposite direction. hen the gears T2 and 66 are in meshxas shown in the drawing the end of the spring lever 84; is in the notch 85 of the sectorSG, the lifting mechanism and arm is being rotated by the direction action of the train of gears. I hen the gear 72"ispivoted to mesh with the gear 82 the lifting mechanismand arm are being rotated indirectly by the reverse action of the train of gears 76, 77, 78 and T9. Vi hen it is desired to maintain the gears idle the yoke is pivoted until the end of the spring lever Set engages the notch 87 which is in neutral position. j fTo counteract the strain on the rotatable member 13 due to the'load carried by the liftin arm, braces 88 are provided and at-.

' tached at one endto the movable collar 89 and at the opposite'end to tl'ieframe-work as shown in Fig. 4:. Collar means 90 or the like can be used if desired to hold the complementary portions of the ball race from spreading apart.

lt'ivill be noted from the showing in the drawing and the direction of the operation of the machine that means are employed to rotate the lifting arm and mechanism there by forcing it to rotate with a certain radius to convey material or a load of any kind to certain or predetermined points in either direction by the manipulation of the lever 83 which operates the yoke 68 to throw the gears 72 into or out of mesh with the gears 82 or 66 as desired. by the operator. It will also be observed that means are employed to raise or lower the load or material to any height or plane desired by the manipulation of the yoke 41 forcing the gear 42 to mesh either with the gear 36 or accord ing to whether or not the operator desires to raise or lower the load. The manipulation described of the yoke 41 forces the drum 33 to rotatevin different directions Winding or unwinding the cable 29 thereon to exert a pull on the roller 27 and lifting or controlling the link mechanism attached to the lifting arm.' The arm 14 is connected to and controlled by the supporting arm 17. Attention is called to the fact thatthe mechanism can be rearranged or combined to impart a direct or reverse movement from either side of the yoke mechanism by re-arranging or changing the train of gears as desired. 7 t

The present invention is shown and described as being applied to a frame-work that is applicable to be used for loading or unloading shocks of corn or the like, but is not intended to in any manner limit-the invention for this specificpurpose, as immaterial alterations or changes may be made to perform other work without departing from the spirit of the present invention.
